Network devices like firewalls and switches serve as the front line defense against unauthorised access, and so their secure configuration is essential for protecting data

What Is It?

Network device configuration reviews assess the configuration and rules applied to routers, switches, and firewalls that govern data flow and access within a network. These reviews are pivotal in spotting inconsistencies, outdated protocols, or any deviations from best security practices that could leave the network vulnerable to attacks. By methodically analysing these configurations, organisations can ensure their network devices are optimized for maximum security, thereby safeguarding their digital assets against evolving cyber threats.

What Challenges Can Be Addressed By Network Device Configuration Reviews?

Insecure Protocols

Network devices can utilise a range of different protocols, and not all of them are secure. Certain protocols may transmit traffic in plain text, allowing attackers to intercept and read sensitive data. Other protocols may use weak authentication mechanisms which an attacker can abuse to gain access to unauthorised resources.

Out of Date Firmware and Software

Hardware manufacturers regularly release security updates for their products to remediate newly discovered vulnerabilities. Not applying these updates can leave devices vulnerable and at risk of compromise by an attacker. Network device configuration reviews ensure that all devices are up to date and free from known vulnerabilities.

Weak or Default Passwords

The management interface for network devices is usually secured through the use of a password, and as such, ensuring this password is adequate is essential for preventing unauthorised modification of the device’s configuration. Default passwords are known by attackers and are frequently abused, and weak passwords can easily be guessed.

in Network Protocols

Firewall rules are a critical component of network security, acting as gatekeepers to control incoming and outgoing traffic based on predefined security policies. However, when these rules are incorrectly implemented—either too broadly, allowing unnecessary access, or too restrictively, blocking legitimate traffic—they can compromise the network’s security posture and operational efficiency.

Weak Encryption Configurations

Weak encryption configurations can significantly undermine the security of data transmission, making it easier for attackers to decrypt sensitive information. Using outdated encryption algorithms or improperly configured encryption protocols can leave data exposed and vulnerable to interception or breaches.

Inadequate Logging
and Monitoring

Logging and monitoring misconfigurations in network devices can significantly undermine an organisation’s security posture. If logs are not properly secured, they can be accessed by unauthorised individuals, potentially exposing sensitive information about the network’s configuration and activity. Furthermore, inadequate logging levels may result in missing critical alerts about malicious activities or system errors, while excessive logging can overwhelm storage resources, leading to important information being overwritten or ignored.

The Forfend Methodology:

Configuration File Assessment – The configuration files for each device will be reviewed using a combination of automated and manual techniques. This will identify a range of potential misconfigurations that may allow for unauthorised access to corporate resources.

Firewall Ruleset Review – This process involves examining the ruleset to identify overly permissive or outdated rules that could allow malicious traffic to pass through, thereby ensuring that only legitimate traffic is permitted in alignment with the organisation’s security policies.

Segmentation Testing – Forfend consultants will finally scan the network to ensure that the firewall rules and segregation are being implemented correctly, and no opportunities for unintended resource access is possible.
